Enhanced security fence and method of construction and installation

Abstract

An enhanced security fence for use in high security situations is provided. The fence is made of high strength materials that are preferably welded together in a convenient location and sent as prefabricated sections to the installation location to form an all welded bracket-less perimeter barrier fence system. Posts with section hangers are provided and installed at a perimeter, and the prefabricated panels are quickly and securely attached to the posts. The panels can be friction fit to the posts and, if desired welded thereto. The invention includes a method of creating an enhanced security fence, that includes prefabrication of panels and rapid fitting and securing the panels to posts to more quickly create a secure perimeter in places having difficult environments.

What is claimed is: 
     
       1. An enhanced security fence having at least one secure side impervious to disassembly of the fence, comprising:
 a plurality of fastening members, comprising elements adapted to be assembled together to form fasteners; 
 a plurality of posts; 
 a plurality of prefabricated sections slideable together to form a frictionally fitted perimeter, each section comprising;
 at least one generally rectangular mesh panel having a top, a bottom, a left side and a right side; 
 at least two structural cross members configured, at least one at the top of the mesh panel and one at the bottom of the mesh panel, to hold the at least one mesh panel therebetween; 
 a first structural side member and a second structural side member, the first structural side member and second structural side member each affixed to the structural cross-members to together form a frame holding the mesh panel therein, the structural side members each having cooperative engagement flanges for slideable engagement of one the plurality of prefabricated sections with another; and 
 
 means for at least one of the plurality of prefabricated sections to engage at least one other of the plurality of prefabricated sections in a frictional engagement, the combined prefabricated sections being fastened, using the fasteners, to one or more of the plurality of posts, with none of the fasteners being exposed to disassembly on the secure side of the fence, to form a fence. 
 
     
     
       2. The enhanced security fence of  claim 1 , wherein the prefabricated sections are welded to the posts and one another. 
     
     
       3. The enhanced security fence of  claim 1 , wherein the mesh panels, structural side members and structural cross members are made from metal. 
     
     
       4. The enhanced security fence of  claim 3 , wherein the metal is steel. 
     
     
       5. The enhanced security fence of  claim 1 , wherein the mesh panels, structural side members and structural cross members are made of alloys. 
     
     
       6. The enhanced security fence of  claim 1 , wherein the structural cross members and structural side members define channels hidden from the secure side of the fence to hold and secrete wiring and/or cables to provide electronic features to the fence. 
     
     
       7. An enhanced security fence having at least one secure side impervious to disassembly of the fence, comprising:
 a plurality of fastening members, comprising elements adapted to be assembled together to form fasteners; 
 a plurality of posts; 
 a plurality of prefabricated sections slideable together to form a frictionally fitted perimeter, each section comprising:
 at, least one generally rectangular mesh panel having a top, bottom, a left side and a right side; 
 at least two structural cross members configured, at least one at the top of the mesh panel and one at the bottom of the mesh panel, to hold the at least one mesh panel therebetween, a first structural cross member forming an upper edge and a second structural cross member forming a bottom edge; 
 a first structural side member and a second structural side member, the first structural side member and second structural side member each affixed to the structural cross-members to together form a frame holding the mesh panel therein, the structural side members each having cooperative engagement flanges for slideable engagement of one of the plurality of prefabricated sections with another; 
 the first cross member and second cross member and the first side member and the second side member being welded together to form a rectangle with the at least one mesh panel welded therewithin to form a panel; and 
 
 means for at least one of the plurality of prefabricated sections to engage at least one other of the plurality of prefabricated sections in a frictional engagement, the combined prefabricated sections being fastened, using the fasteners, to one or more of the plurality of posts, with none of the fasteners being exposed to disassembly on the secure side of the fence, to form a fence. 
 
     
     
       8. The enhanced security fence of  claim 7 , wherein the at least one mesh panel is two mesh panels. 
     
     
       9. The enhanced security fence of  claim 8 , including a vertical support member bisecting a horizontal axis of the panel and being attached to the first structural cross member and second structural cross member, the two mesh panels being welded to the structural side members, the structural cross members and the vertical support member. 
     
     
       10. The enhanced security fence of  claim 7 , wherein the at least two structural cross members are four structural cross members, one placed at the top of the panel, one placed at the bottom of the panel, one at ⅓ of the height of the panel and one at ⅔ the height of the panel. 
     
     
       11. The enhanced security fence of  claim 7 , wherein the side members comprise one each of a Tee-rail and angle iron. 
     
     
       12. The enhanced security fence of  claim 7 , wherein the structural cross members and structural side members define channels hidden from the secure side of the fence to hold and secrete wiring and/or cables to provide electronic features to the fence.
